For volcanic samples between 15 and 30 grains were mounted depending on the sample yield. Zircons were mounted together with FC-1 standard zircon (Duluth Gabbro). Analyses were performed by LA- MC-ICP-MS using a Nu-Plasma® at the Center for Isotope Geoscience Laboratory in the University of Florida. The zircon grains were ablated with a New Wave® 213 nm ultraviolet laser, using a laser spot size of 20* µm for U/Pb and 40 µm for Hf. Every 10 ablations of unknown zircon samples for U/Pb were bracketed by two ablations of the FC-1 standard. We use the ²⁰⁶Pb/²³⁸U ages for zircons younger than 850 Ma and the ²⁰⁷Pb/²⁰⁶Pb ages for older data. In addition, Hf isotopic measurements were made on the same zircons analyzed for U/Pb. We selected 10 zircons for every age population cluster recorded in the U/Pb analysis considering the error (smallest errors) and grain size. Isotopic data were reduced using CALAMARI (in-house data reduction excel spreadsheet) and then plotted using Isoplot 4.5 (Botero-Garcia et al, 2019).
